In addition, in the description of this embodiment, unless otherwise specified, the meaning of "a plurality" is two or more.
[0044] Embodiment 1
[0045] As Figure 1 shown, in this embodiment, a method for measuring the rod position of a control rod in a reactor is provided, including:
[0046] S11: Obtain the initial position of the control rod;
[0047] S12: Based on the driving mechanism, drive the control rod to move towards the target position at a first moving speed, and obtain the actual displacement of the control rod based on the laser rangefinder;
[0048] S13: In response to the actual displacement meeting the preset displacement, control the driving mechanism to stop working and determine that the control rod has moved to the target position; in response to the actual displacement not meeting the preset displacement, control the driving mechanism to continue driving the control rod to move towards the target position at the first moving speed, and re-execute the step of obtaining the actual displacement of the control rod based on the laser rangefinder until it is determined that the control rod has moved to the target position.
[0049] Through the method for measuring the rod position of the control rod in the reactor provided by the present disclosure, millimeter-level measurement accuracy of the rod position of the reactor control rod can be achieved to ensure the accurate determination of the control rod position. At the same time, the scheme provided by the present disclosure can also achieve a millisecond-level response time and quickly respond to changes in the control rod position; by adopting a non-contact measurement method, physical interference to the control rod is avoided, further ensuring the accuracy of the control rod position measurement.
[0050] In this embodiment, after the step of in response to the actual displacement not meeting the preset displacement, the method for measuring the rod position further includes:
[0051] In response to the actual displacement of the control rod not changing at different moments within the first preset time, it is determined that a fault occurs during the movement of the control rod.
[0052] In this embodiment, the drive mechanism drives the chain to rotate, and the control rod is hung directly below the chain. When the chain moves, there will be free swinging, that is, the control rod is stuck in the sleeve. At this time, the control rod will not move with the rotation of the chain; or when the drive mechanism drives the chain to rotate and the chain idles or jumps, etc., the control rod will not move with the rotation of the chain either.
[0053] Therefore, when the displacement of the control rod does not change within a certain period of time, it can be determined that a fault has occurred during the movement of the control rod.
[0054] The method for measuring the position of the control rod in the reactor provided by the present disclosure can quickly detect and respond to faults such as "idling", "chain jumping", "chain jamming", and "rod jamming" during the operation of the control rod connected by a flexible chain or a wire rope, which helps to improve the operation safety and reliability of the reactor and reduce the impact of faults on the performance of the reactor.
[0055] In this embodiment, after the step of determining that a fault has occurred during the movement of the control rod, the method for measuring the rod position further includes:
[0056] Generating fault information; and / or generating a fault response strategy.
[0057] In one implementation, the generated fault information can be data that details the fault situation when it is detected that a fault has occurred during the operation of the control rod, so that the operator can take relevant countermeasures according to the specific fault information to ensure the safe operation of the reactor.
[0058] Among them, the data that details the fault situation at least includes the fault type (such as "idling", "chain jumping", "chain jamming", "rod jamming", etc.), the time when the fault occurred (such as the timestamp information when the fault occurred), and the relevant parameters of the current drive mechanism (such as the moving speed and displacement deviation of the control rod), etc.
[0059] In one implementation, the fault response strategy is the relevant measures that the operator can take after detecting the fault, so as to reduce the impact of the fault on the performance of the reactor and ensure the safe operation of the reactor.
[0060] Among them, after the step of generating fault information and / or generating a fault response strategy, the method for measuring the rod position further includes:
[0061] Generating a fault warning message.
[0062] In one implementation, the generated fault warning message can be at least one of a sound message and a display message, so as to be used to remind the operator to take relevant measures in time to ensure the safe operation of the reactor.
[0063] Such as Figure 2As shown in the figure, the control device of the control rod in the entire reactor consists of a speed reducer a, a laser rangefinder b, a control rod c, a chain d, a sleeve f, and a steel shell f. Among them, the speed reducer a, the laser rangefinder b, the control rod c, the chain d, and the sleeve f are all arranged inside the steel shell f, and the entire steel shell f contains a radiation and radioactive gas atmosphere. The laser rangefinder b is arranged in the speed reducer a. The speed reducer a drives the chain d to move, thereby driving the control rod c to move in the sleeve f, and the laser rangefinder b obtains the displacement information of the control rod in real time.
[0064] The laser measurement method consists of a laser (placed in the laser rangefinder), a laser transmission optical fiber, a signal acquisition optical fiber, and an optical fiber transceiver controller (placed in the laser rangefinder). The pulse laser measurement method is adopted. The picosecond laser pulse is led to the test area at the end of the control rod through the laser - optical fiber for the transmission and reception of the laser. By collecting the reflected laser signal of the emitted laser pulse and the signal acquisition algorithm, the rod position measurement information with large stroke, high precision, and fast speed can be obtained.
[0065] However, due to the following problems: the ambient temperature field of the optical fiber is variable temperature, and the variable temperature range is large; the environmental conditions where the optical fiber is located have strong radiation; the temperature of the reflective end face of the optical fiber ranges from room temperature to 600 °C, which has a great influence on the optical flux feedback of laser ranging; the measured stroke range is large, not less than 4 meters; the length of the transmission optical fiber is very long and there are intermediate transfers, usually 20 meters.
[0066] Therefore, in this embodiment, an optical fiber temperature compensation algorithm needs to be added to compensate for the loss of measurement accuracy caused by the change of the optical fiber temperature field; the laser has been moved out of the irradiation area, and the requirements for the electronic equipment of the laser have been downgraded in terms of working conditions;
[0067] At the same time, in this embodiment, radiation - resistant optical fibers also need to be used, and the service life of the optical fiber is improved; the additional optical fiber waveguide of the laser will introduce displacement measurement errors. By measuring the laser emission - reception data multiple times, the background value is obtained. By deducting the background, the displacement measurement error introduced by the optical fiber length can be effectively eliminated; the temperature of the reflective end face of the optical fiber ranges from room temperature to 600 °C, which will cause a deviation of the reflected wave flux and reduce the measurement accuracy. The error is reduced through the flux compensation algorithm; the response time of the laser terminal processing is improved, and the distance measurement is completed within milliseconds.
[0068] Therefore, the rod position measurement method in this embodiment further includes:
[0069] In response to the actual environmental parameters not meeting the preset environmental parameters, a matching preset environmental compensation algorithm is used to compensate for the errors of the laser rangefinder;
[0070] Among them, the preset environmental parameters include at least one of environmental temperature information, optical fiber information, and optical flux information.
[0071] Among them, the preset environmental compensation algorithm includes at least one of a fiber optic temperature compensation algorithm, a displacement error compensation algorithm, and a flux compensation algorithm.
[0072] The laser rangefinder may have measurement errors under different environmental conditions; for example, when the optical fiber is at different temperatures, its transmission characteristics will change, resulting in a decrease in measurement accuracy; or, the change in the length or the characteristics of the optical fiber itself will affect the accuracy of displacement measurement; or, the change in the temperature of the reflection end face of the optical fiber will affect the flux of the reflected light, thereby affecting the measurement accuracy.
[0073] In this embodiment, when the optical fiber is at different temperatures, due to the thermo-optic effect, its physical properties such as refractive index and length will change, thereby affecting the transmission characteristics of light, that is, the temperature change will cause the characteristics of the optical fiber to change, thereby reducing the measurement accuracy.
[0074] Therefore, the fiber optic temperature compensation algorithm can be: according to the real-time monitored temperature value, establish a relationship model between the fiber optic characteristics and the temperature. For example, a functional relationship between the refractive index of the optical fiber and the temperature can be established. Calculate the corresponding compensation value through the compensation model and correct the output signal of the sensor. For example, if the increase in temperature causes a change in the refractive index of the optical fiber, the change can be compensated by adjusting the signal processing algorithm, thereby improving the measurement accuracy.
[0075] In this embodiment, when the laser is transmitted through the optical fiber, factors such as the length and bending degree of the optical fiber will affect the propagation path and time of the light, and the change in the length of the optical fiber (for example, due to temperature change) will cause a change in the optical path, thereby introducing a displacement measurement error.
[0076] Therefore, the displacement measurement error compensation algorithm for the optical fiber can be: without displacement change, perform laser emission and reception measurements multiple times to obtain a set of data as the background value. In actual measurement, compare the signal obtained each time with the background value and deduct the influence of the background value, thereby eliminating the displacement measurement error introduced by the change in the length of the optical fiber.
[0077] In this embodiment, when the temperature of the reflection end face of the optical fiber rises from room temperature to 600 °C, the intensity (flux) of the reflected light will change, and the change in the flux of the reflected light caused by the temperature change will reduce the measurement accuracy.
[0078] Therefore, the flux compensation algorithm can be: establish a relationship model between the flux of the reflected light and the temperature of the reflection end face. For example, measure the change in the intensity of the reflected light at different temperatures and establish a temperature-flux relationship curve. In actual measurement, according to the real-time temperature of the reflection end face, calculate the corresponding compensation value through the flux compensation model and correct the output signal of the sensor. For example, if the increase in temperature causes an increase in the flux of the reflected light, the change can be compensated by adjusting the signal processing algorithm, thereby improving the measurement accuracy.
[0079] Through the error compensation of the laser rangefinder, the accuracy of the measurement of the control rod position is further ensured.
